Slip-resistant and portable scanner

Abstract

A slip-resistant and portable scanner for scanning a document placed on a document platen includes a housing, a scan window, and a scanning module and a slip-resistant structure. The scan window is mounted on the housing to closely face the document. The scanning module is disposed in the housing to scan the document through the scan window. The slip-resistant structure is disposed on and attached to a surface of the scan window facing the document and in contact with the document or the document platen. Thus, it is possible to prevent the scan window from slipping relatively to the document and enhance the scan quality and convenience.

1. A slip-resistant and portable scanner for scanning a document placed on a document platen, the scanner comprising:
 a housing; 
 a scan window mounted on the housing to closely face the document; 
 a scanning module disposed in the housing to scan the document through the scan window; and 
 a slip-resistant structure disposed on and attached to a surface of the scan window facing the document and in contact with the document or the document platen, so as to prevent the scan window from slipping relatively to the document, wherein the slip-resistant structure comprises a slip-resistant stick surrounding and defining a rectangular region, and the slip-resistant stick is disposed in a ring-shaped groove of the scan window. 
 
   
   
     2. The scanner according to  claim 1 , wherein the housing comprises a transparent bottom facing the scan window. 
   
   
     3. The scanner according to  claim 1 , wherein the rectangular region corresponds to a maximum scan region of the slip-resistant and portable scanner. 
   
   
     4. A slip-resistant and portable scanner for scanning a document placed on a document platen, the scanner comprising:
 a housing; 
 a scan window mounted on the housing to closely face the document; 
 a scanning module disposed in the housing to scan the document through the scan window; and 
 a slip-resistant structure disposed on and attached to a surface of the scan window facing the document and in contact with the document or the document platen, so as to prevent the scan window from slipping relatively to the document, wherein the slip-resistant structure comprises two slip-resistant sticks, and each of the slip-resistant sticks is disposed in an L-shaped groove of the scan window. 
 
   
   
     5. The scanner according to  claim 4 , further comprising:
 a USB connection port to be connected to a host; and 
 a power management unit connected to the USB connection port to receive and manage a host power, which comes from the host, for an operation of the slip-resistant and portable scanner. 
 
   
   
     6. The scanner according to  claim 4 , further comprising:
 a battery for supplying a battery power for an operation of the slip-resistant and portable scanner. 
 
   
   
     7. The scanner according to  claim 4 , further comprising:
 a remote transceiver, which is signal-connected to a host in a wireless manner and for transmitting an image signal, which is obtained when the scanning module scans the document, to the host. 
 
   
   
     8. The scanner according to  claim 4 , further comprising:
 a memory device for storing an image signal obtained when the scanning module scans the document. 
 
   
   
     9. The scanner according to  claim 4 , wherein the scanning module contacts the scan window and slides under the scan window. 
   
   
     10. The scanner according to  claim 4 , wherein each of the slip-resistant sticks is L-shaped and the slip-resistant sticks define a maximum scan region of the slip-resistant and portable scanner. 
   
   
     11. The scanner according to  claim 10 , wherein the slip-resistant sticks are located on a diagonal of the maximum scan region. 
   
   
     12. The scanner according to  claim 10 , wherein the housing comprises a transparent bottom facing the scan window.
